Former X Factor host Olly had dated Francesca for three years, but the couple split in September last year. At the time, reports claimed Olly and Francesca split abruptly, blaming his busy working schedule and the stresses of juggling his singing career with hosting The X Factor.
Following their break up, Olly said it had been a "difficult time" for him, and now, it sounds like still hasn't completely moved on from his former flame.
Speaking to The Sun on Sunday, Olly revealed he isn't yet over Francesca.
He said: "I'm not over it. I don't think anyone is ever over a break-up. You're always going to think about them and care about them."
"It's like you've lost someone," he explained. "Like you're grieving... because they were there all of the time and then they're not."
Olly added that he has channelled the loneliness he felt after breaking up with Francesca into his new music. He said: "Writing the album has been like therapy in a way as I got upset in the sessions. Maybe it will be difficult for her to listen to."
Despite splitting with Francesca eight months ago, Olly hasn't ruled out a reunion with his ex-girlfriend in the future.
Back in November, he said: "After breaking up after three years it is a bit of a strange time. You don't know if you might end up going back, getting back with someone... you don't know what the future holds."
While he had still be dating Francesca, Olly had confessed that he liked her because she lived a life out of the spotlight.
He told Fabulous magazine: "We try to keep things private so Francesca can have a normal life. That's why I like her and find her attractive. I don't want her to be plastered in newspapers and everyone to know what we're up to."
Since becoming single again, Olly has been linked to his close pal and former X Factor co-host Caroline Flack - however, the pair have always insisted they are just friends.
